AS-International is the trade organization for AS-Interface users worldwide. The organization was founded in 1991 by the founding fathers of AS-Interface, each being an industrial company with different strategic and economic interests. They knew that the new technology can only be successful if an independent user organization is in charge of introducing the new technology to potential users. AS-International was born. The organization’s mission was very vaguely described as “The promotion of bus-able interfaces for binary sensors and actuators.”

The EtherCAT Technology Group (ETG) is the forum in which key user companies from various industries and leading automation suppliers join forces to support, promote and advance the EtherCAT technology. The EtherCAT protocol uses an officially assigned EtherType inside the Ethernet Frame. The use of this EtherType allows transport of control data directly within the Ethernet frame without redefining the standard Ethernet frame. The frame may consist of several sub-telegrams, each serving a particular memory area of the logical process images that can be up to 4 gigabytes in size. Addressing of the Ethernet terminals can be in any order because the data sequence is independent of the physical order

ODVA is a global association whose members are comprised of the world’s leading automation companies. ODVA’s mission is to advance open, interoperable information and communication technologies in industrial automation. ODVA recognizes its media independent network protocol, the Common Industrial Protocol or “CIP” – and the network adaptations of CIP – EtherNet/IP, DeviceNet, CompoNet and ControlNet – as its core technology and the primary common interest of its membership. ODVA’s vision is to contribute to the sustainability and prosperity of the global community by transforming the model for information and communication technology in the industrial ecosystem. For future interoperability of production systems and the integration of the production systems with other systems, ODVA embraces the adoption of commercial-off-the-shelf (COTS) and standard, unmodified Internet and Ethernet technologies as a guiding principle wherever possible. This principle is exemplified by EtherNet/IP – the world’s number one industrial Ethernet network.

LS Industrial Systems has developed RAPIEnet as a new industrial communications bus for use with its PLC (Programmable Logic Controller) systems. The company says that in so doing the design has avoided the complications of hubs and switches and the accompanying excessive cabling required by established Ethernet technology. RAPIEnet, while still compatible with the preexistent Ethernet standards, transmits data at a 1 GB-per-second speed and in case of a communications failure can repair the error 30 times as faster. It can be utilized in a variety of fields operated by automation systems such as semi-conductor and automobile manufacturing, or nuclear energy development.
